QCD higher-order radiative corrections and precision determinations of quark masses

夸克是存在于原子核中的基本粒子。在这个研究项目中，我们进行了精确的理论计算来解释由夸克和它的反粒子组成的物理系统的本质。特别是，我们完成了十多年来一直要求的夸克间力的计算。这一结果具有广泛的应用，并已应用于夸克质量和其他物理参数的初步测定。此外，我们还构建了一个在当前LHC实验中精确测定顶夸克质量所必需的理论框架。

Quarks are elementary particles which reside in atomic nuclei. In this research project, we performed precise theoretical computations for explaining the nature of the physical systems composed by a quark and its anti-particle. In particular, we completed computation of the interquark force which has been demanded for more than a decade. The result has a lot of applications and has already been applied to preliminary determinations of quark masses and other physical parameters. Furthermore, we constructed a theoretical framework which is necessary for determining the top quark mass accurately at the current LHC experiment.
